GroEL retards the re-folding of apo-α-lactalbumin by interacting with the molten globule state of the protein. The binding constant was estimated to be in the order of 105M−1by analyzing the kinetic data quantitatively and was found to be much weaker than the binding between GroEL and disulfide-bond reduced α-lactalbumin, whose binding constant is in the order of 107M−1. Our present results, together with the previous results, suggest that the state recognized by GroEL is not unique and that the binding strength varies with the state of a target protein. The binding between GroEL and the molten globule state of apo-α-lactalbumin becomes stronger with an increasing salt concentration; the binding constant is increased tenfold (from 105to 106M−1) by an increase in salt concentration from 0.05 to 0.25 M. The study of the effect of GroEL on the re-folding kinetics of holo-α-lactalbumin, which is represented by a bi-phasic process, shows that the slow phase is affected by GroEL in the same manner as observed in the apo-α-lactalbumin re-folding but that the fast phase is not affected by GroEL at all. This indicates that the binding rate of GroEL is faster than the slow phase but slower than the fast phase of the re-folding, and the bi-molecular rate constant of GroEL binding to the molten globule state of α-lactalbumin was estimated to be in the order of 106M−1s−1.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1006/jmbi.1996.0290"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1006/jmbi.1996.0290","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1996 Academic Press"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-2836 ","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KATSUMATA, Kumiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKAZAKI, Akira "}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUWAJIMA, Kunihiro "}],"nameIdentifiers":[{}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effect of GroEL on the Re-folding Kinetics of α-Lactalbumin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of GroEL on the Re-folding Kinetics of α-Lactalbumin"},{"subitem_title":"Effect of GroEL on the Re-folding Kinetics of α-Lactalbumin","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["323"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-03-10"},"publish_date":"2014-03-10","publish_status":"0","recid":"4273","relation_version_is_last":true,"title":["Effect of GroEL on the Re-folding Kinetics of α-Lactalbumin"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:25:46.361284+00:00"}
